Brake Switch - TCC: Description and Operation
CIRCUIT DESCRIPTION
The purpose of this circuit is to prevent the engine from stalling, while driving in lock-up condition, when brakes are suddenly applied.
When the brake pedal is operated, this switch sends a signal to the ECM. Then the ECM cancels operation of the lock-up clutch while braking is
in progress.
